摘要： A tantalum powder, a tantalum powder compact, a tantalum powder sintered body, a tantalum anode, an electrolytic capacitor and a preparation method for tantalum powder. The tantalum powder contains boron element, and the tantalum powder has a specific surface area of greater than or equal to 4 m2/g; the ratio of the boron content of the tantalum powder to the specific surface area of the tantalum powder is 2~16; the boron content is measured in weight ppm, and the specific surface area is measured in m2/g; Powder that can pass through a ρ-mesh screen in the tantalum powder accounts for over 85% of the total weight of the tantalum powder, where p=150~170; and the tantalum powder with high CV has a low leakage current and dielectric loss, and good moldability.

摘要： It is an electrode material that is used as an electrode contact of a vacuum interrupter and that contains one or more parts by weight of a heat-resistant element and one part by weight of Cr, the remainder being Cu and an unavoidable impurity. A part of Cr powder and the heat-resistant element powder are mixed together, and this mixed powder is sintered such that a peak corresponding to Cr element disappears in X-ray diffraction measurement. A solid solution powder obtained by pulverizing a sintered body of the heat-resistant element and Cr obtained by the sintering is mixed with the remaining Cr powder, and this mixed powder is shaped and then sintered. A sintered body obtained by this sintering is infiltrated with Cu.

摘要： The present invention provides a chemical conversion body which enables production of an electrolytic capacitor and a device exhibiting high binding strength, high capacitance, and little fluctuation in capacitance, while retaining a specific surface area; and a production method therefor. A capacitor according to the present invention uses a chemical conversion body obtained by sintering a niobium granulated product obtained by a production method comprising mixing niobium hydride and a niobium-aluminum intermetallic compound, pulverizing the mixture, and allowing the mixture to agglomerate by heat treatment to thereby form a granulated product; and subjecting the sintered body to the electrolytic oxidation to form a dielectric layer on the surface of the sintered body; in which chemical conversion body the sites of aluminum localization having a size of 0.1 µm to 0.5 µm are scattered in the depth of less than 0.06 µm from the surface of the dielectric layer. Nb 2 Al and Nb 3 Al can be preferably used as a niobium-aluminum intermetallic compound.

摘要： A tantalum sputtering target, wherein, on a sputtering surface of the tantalum sputtering target, an orientation rate of a (200) plane exceeds 70%, an orientation rate of a (222) plane is 30% or less. By controlling the crystal orientation of the target, effects are yielded in that the discharge voltage of the tantalum sputtering target can be reduced so that plasma can be more easily generated, and the voltage drift during deposition can be suppressed.

摘要： A thermoelectric conversion module includes a p-type thermoelectric conversion member (111) and an n-type thermoelectric conversion member (112) that contain Sb, and an electrode member (120) that is joined to the p-type thermoelectric conversion member (111) and the n-type thermoelectric conversion member (112), composed of an alloy of Cu and a metal material M1 having a lower thermal expansion coefficient than that of Cu, and includes two or more crystalline phases composed of Cu and M1. Therefore, it is possible to improve durability while realizing the properties required for the thermoelectric conversion module.
